TTi (Thurlby Thandar Instruments) has extended their PSA-T series of
low-cost highly portable RF spectrum analyzers with the launch of the
PSA2701T.
The new model has a frequency range of 1MHz to 2700MHz and a selling
price of £995. As well as being lower cost, it is considerably smaller,
lighter, and lower power than other RF spectrum analyzers currently
available. Despite this, it offers a high resolution (480 x 320 pixel)
backlit colour TFT display.
The PSA2701T offers resolution bandwidths of 1MHz, 280kHz or 15kHz, and
a typical best noise floor of –96dBm. Sweep modes include continuous,
single, peak hold and average (up to 256 sweeps). Sweep parameters can
be set in terms of centre plus span or start plus stop to 1 kHz
resolution. A zero span mode with AM or FM demodulation is also
provided.
Dual markers are incorporated with simultaneous readout of absolute
amplitude and frequency plus difference values. Markers can be scrolled
manually, or set to automatically find and track peaks. Amplitude limit
lines can be created and stored, and two limit lines can be displayed
simultaneously. Amplitude measurement can be in dBm or dBµV.
A reference trace can be displayed simultaneously with live trace,
clearly differentiated by colour. The reference trace is automatically
shifted and scaled to match the current sweep parameters when they are
changed.
Any number of waveforms and settings can be stored to permanent memory
using an SD flash memory card. Bitmap images of the whole screen can
also be stored for viewing or printing.
Low power consumption offers more than four hours of continuous
operation from a charge. The analyzer can also be set to turn off
automatically after a user defined delay from the last key press,
extending battery life further.
The PSA2701T offers many additional features from its integrated Palm
T|X handheld computer. These include word processing and spreadsheets
(compatible with Microsoft Word and Excel), contacts and appointments
diary, multi-function calculator, picture viewing, audio and video
players, plus web and email access via WiFi and Bluetooth.
Until now, the PSA-T series spectrum analyzers have been limited to
1.3GHz maximum. The new PSA2701T covers almost the full UHF band
including the 1.5GHz to 1.7GHz bands used for mobile satellite links and
GPS, the 1.7GHz to 1.9GHz bands used for PCN/GSM and DECT and the 2.4GHz
to 2.5GHz ISM band used for Wireless LAN, Bluetooth, microwave RFID as
well as other specialist communication bands.
The PSA2701T weighs less than 0.5 kg (1.1 lbs) and measures 170 x 97 x
47 mm (6.7 x 3.8 x 1.85 inches). The weight and dimensions make it a
true handheld instrument, u
The PSA2701T costs £995 in the UK and 1,495 Euros in Continental Europe.
The approximate International price is $1,990.
